Carb recommendation
Hey Guys, Need a carb recommendation for my 1969 Torino Talladega 428CJ/C6. Has a replacement Autolite on there now. These came originally with a Holley 4150 735 CFM carb. Originalty is not as important at this point as drivability. Any ideas? I am on a budget here. So?:MECOOL:
|
Holley LIST-3310 Vacuum secondary 750 CFM - You can't go wrong, it's inexpensive and it's a bolt-on..
|
Sells for around $250.00 and is an excellent choice.
If you want the formula for how to calculate the carb, search carb formula ( I think ). |
Any Holley or Demon 600-750. If you are still at 10.5:1 you might indeed go with the 750 vacuum secondary. It should net you a 20 hp gain over the autolite.

I just replaced my 3310 with an 850 double Pumper, and boy what a difference !
If performance is what you´re after i´d go with the double pumper anytime - your mileage (both fuel and tires) will probably suffer though. |
Thanks all for your replies. One of several issues to resolve on this car. I may wait and go with a Double-pumper. The short block was replaced back in the 70's so the car will never be VIN matching. Have been toying with the idea of dropping in a 460 SVO crate motor (Future).**) So I could use a bigger carb now and use it on the other motor if that ever happens. A partial dissassembly would be necessary to figure out what shortblock is under there. (390 or 428) The original Cobra Jet heads are on this shortblock. Engine sound nice!!! Even with that lame small looking Autolite carb. %/ Thanks again... Dave

Ford doesn't have VIN # on their blocks. All that matters is that it is a 428CJ short block Of the C7** or C8** I'm not sure of casting date but the engines are not like Chebbys with a serial # to match the car.

Hi Naumoff, Actually there is supposed to be a partial VIN on the Transmission and on the Block. You have to know where to look. I am told it is behind the head, as I recall on the passenger side. Thanks for your input. Dave

69Torino,
I am sure that you are already aware of this but just dropping in a 460 is going to involve matching your bell housing and such. The 429/460 engines are of the 385 series and the one you have is the FE series. If you have a short block, there most likely won't be anythng behind the head on the block. That would depend on the block and year. Even if there is anything it really won't tell you much. You could go to a 750 or 800 doublepumper and see how it works out. May have to change some jetting depending on your cam and stuff. But if you go a reasonably stock 460 later, the 800 can be worked to run really well on them and stay streetable. Ron :) |
Hi Ron, Well my post was just kicking around the idea. My budget won't allow much for a while yet. Back in the day these were raced with the Boss 429's. Your correct that that is a 385 truck series engine. Maybe I should just have the block I have redone to 428SCJ spec's? It's supposed to be a low milage replacement block. The car show 57,000 miles. And has sat for a long time. 50 Miles or so since my Father got it and sitting since 1979. Two issues to resolve. Choke adjustment on the Autolite carb and pulling out the axles for new seals. Than it could be driven. I am some what swaying toward a 750 Double pumper at this time. So Ron is it worth having the engine balanced and blueprinted? Should I consider having the heads mildly ported with stainless valves? Dave

Dave,
Depending on the engine builders in your area, the balancing and blue printing are something that you can live without if they want to much to do it. I think in your case the 750 Holly Double Pumper carb would be the best choice since you aren't going with big cams & etc. If the heads are stock, having them pocket ported and the runners cleaned up will gain you around 20 horsepower depending on how rough they are. And the pocket porting is a very easy and simple job. I have stainless valves in mine that the dealer out in when they did all the work and they have been great. I believe that in the long run, you would pay less and gain more by using your block and then just having done to it whatever you want. Check the head numbers. Mine came with the 427 heads and LeMans rods and other low end stuff that was different from the regular 428 CJ. If you have 390 heads, try to find some 428 police heads as the 427 heads are getting harder to locate. As for actually knowing the bore, it would have to be measured to see if it is a 390 or 428 bore. Also look at the cam you have and see what it is. Ron :) |
With a C6, I would think a vacuum secondary carb would be best for drivability and gas mileage. I just took a 650 DP off my Mach 1 with a 390/C6 combo and am replacing it with a Holley 770 Street Avenger. They have Electric choke and Ford kickdown. I’m in the middle of my rebuild so I can’t tell you how it runs yet but I’m hoping for good things.

Hi Timmy, Let me know how that turns out. I'd like to hear about it. As of today I have a clear title to the Talladega. Time to start planning repairs. Still to cold to work on it. Was -10 for several days this last week....... RON61, Have you tried any different rims/tires on your Torino? I have some 15 Inch rims from American Racing. Not sure if the back spacing will work. If you did run 15 Inch rims. What size tire? Thanks Dave
|
Dave,
I haven't changed a thing on my Cobra. It still has the original wheels and tires that came on it from the factory. So I can't tell you about back spacing or anything. You might try the 15" rims and if the back spacing is to much, they make spacers that you can get to help, but then you may have to change the studs for the lug nuts to longer ones. Sorry that I can't help you on that one. :( Ron :) |
Hi Ron, No problem. Thanks for the reply. The American Racing rims are on my daily driver so until the tires are shot (tires to large for the Torino) I will keep the original 14 inch stock rims on the Talladega. Dave
